[OT?] PoPToP Problems



Sorry for posting here fellas (and ladies), but after a week, I'm not getting any replies from the PoPToP list. I'm hoping one or more of you have used PoPToP and can help me get it going. Maybe Alexander Dalloz even has this answer in his almighty brain - he seems to know everything else :)

Here goes - FC3 All Updates and the latest PoPToP installed and receiving requests. All the PoPToP installation steps have been followed as per instructions and versions checked. I do not honestly think the problem lies there.

The problem seems to stem from me running pppd in demand mode or the way I call pppd to dial my ISP (yes I'm on the most wonderful invention called dial-up).

PoPToP sees the incoming connection, but as it hands off to pppd, pppd seems to terminate unexpectantly, and I think it has to do with the way my dial-up is set up, because chat also gets called to dial my ISP when all this happens, even though this is obviously unnecessary, as I am already connected.

While all this is going on, my ppp0 internet connection remains live.

The related log below:

Apparently I'm supposed to see a

Connect: ppp0 <--> /dev/pts/0

Or something like that somewhere (although in my case should it be ppp1?), but pppd dies before it hits that stage.

I don't seem to have a pppd log anywhere even though option DEBUG=yes is set.

Any ideas anyone? At this stage I'll take anything, otherwise I'm going to have to dump it in favour of some other VPN road warrior solution which is not going to be anywhere near as convenient when you consider PPTP is built into Windows XP clients.

Regards,
Ed.
